Application filed July 24, 1909, Serial No. 509,858.

To all 'wizom 1'7, may concern .Be it known that I, Josnrir B. HAMILTON, a citizen of the United States. residing at San Antonio, in the county of Beyar and State of Texas, have invented a new and useful Colla Shaping: .Machine. of which l L a specification.

This invention relates to improven'ients in 1 machines for shaping".collars, and the particular purpose of the invention is to produce a machine of few parts which may be easily operated and by which fold-over col perfectly shaped. The preferred embodiment of my invention is illustrated in the accompanying drawings. and the invention consists in certain novel features of the same which will be hereinafter first fully described and then distinctly claimed.

In the drawings, Figure 1 is a side eleva tion of the machine showing the collar holding ring lowered from the steam shaping chest. Fig. 2 is a front elevation showing a collar holding ring moved into der the shapingchest. of the machine, Fig. section. Fig. 5 I collar-holding tional view. l

The frame of the machine comprises a base plate 1 and a standard 2 rising therefrom to a proper height to permit the working parts to he readily controlled by the operator. the base plate being securcll by belts or otherwise to the door of the laun- I dry. will be readily understood. Upon the front side of the standard 2 are guides or bearings 23 in which is mounted a recipi'ocating rod fl having a collar 5 secured thereto bv a set screw 6 between. the bearings, as clearly shown. while around the rod between said collar and the lower bearing l place a butter 7 of rubber or other elastic material which receives the impact ot the collar so as to cushion the blow of the reciprocatorv rod upon the descent of the same. Upon the upper local-in; 3 is a guide or bracket 8 in the outer end of which a pin 9 is adapted to move. the said pin depend- I position un- Fig. 3 is a plan view -l is a detail horizontal is a transverse section ot a ring. Fig. 6 is a detail secing from one of a. pair of divergent arms 10 which are secured to the upper end of the rod 4. The said arms 10 serve as guides upon which slides 11 are movablv mounted.

111g rings 12 which are swiveled upon the slides sons to be easily rotated at the will l Specification of Letters Patent.

of the opera-tor to permit the Work of inserting the collar. to be most conveniently and expeditiously performed. These collar holding members consist of metal rings of proper dimensions having springs or other holding fingers 13 secured on their inner sides to engage the inner edge 01' fold of'the collar and thereby hold the collar over the upper edge of the ring in position to be inserted into the shaping groove of the steam drum 14, as 'ill be readily understood. The steam drum 14 is a hollow body having a Vshaped groove 15 in its underside and provided with suitable steam inlet and outlet pipes 16 and 17 so that the drum maybe readily heated and maintained at the desired temperature. The drum is rigidly secured to the upper end of the standard 2 which is formed into an overhanging arm in order that the drum may be brought into the proper position to be readily engaged by the collar holding rings. Two of the collar holding rings are provided in order that while the collar on one ring is being shaped. acollar may be fitted upon and secured to the other ring.

In order to raise the collar holding ringinto engagement with the steam drum and to lower it. from said engagement. I employ treadles 1S and 19 which are mounted upon the base plate 1. The trcadlc 19 has its inner or upper end 'iivotally attached to a socket 20 in which a pin 22. pivotallv attached to the lower end of the reciprocatiim rod by means of a knuckle 2 3. plays. a spring 2t being coiled around the said pin between the socket. and the knuckle so as to hold the parts in their proper operative positions and permit a slight lostmotionto prevent breakage ot the pivotal connections. A bracket projects forward from the standard 2 between the trcadles. and upon the forward end of the said bracket is pivoted a knocltcr 96 in the form of a short bar eX- tending transversely in "front of the treadles and adapted to be struck by the upper end of that trcadle which depressed by the operator so that the knoclrer will he vibrated and its opposite end caused to strike the other treadle and thereby throw the said treadle in the opposite direction.

It is thought the operation and advantages of my improved machine will be readily mnderstood and appreciated from the foregoing" description, taken in connection with the'accompanying drawings. The

operator places a collar over the upper edge of one of the collanholding rings 12 and then slides the said ring toward the inner end of the arm 10 upon which the said ring is mounted. The treadle 19 is then depressed so as to swing its inner end forward and thereby cause the reciprocating rod carrying the diverging arms 10 to rise so that the collar will forced into the recess in the underside oi. the steam chest and will, consequently, be thoroughly smoothed and shaped. The ring 12 is left in its engagement with" the steam chest while another collar is placed in position upon the other ring 12, and after the collar has been thoroughly ironed, the trcadle 18 is operated to lower the reciprocating rod and thereby bring the ring downward out of engagement with the steam chest. This ring is then moved out from under the steam chest and the ring carrying the unfinished collar is moved into position under the steam chest that the collar will be in position to enter the groove in the same. When the treadle w 19 is depressed so as to raise the reciprocating; rodthe inner end ot the said treadle will he brought against the knocker so as to vibrate the said knocher and cause the o 'i 'iositc end of the same to strike the end of the treadle l8 and thereby raise the said treadlc into position to he engaged by the operator. After the collar hasheen pressed, the operator depresses the trcadle 18 and thereby actuates the lniocker so as to carry the same against the upper end of the treadle 19-and throw the said end iu- Ward so that the reciprocating rod will be brought downward to lower the collar holding ring, as will be readily understood.

The device is extremely simple in its construction, can be manufactured at a slight cost, is easily operated, and efiiciently accomplishes the desired results.

Having thus described my inventionpwhat I claim is 1. In a collar-shaping machine, the combination of a hollow drum having a collar receiving groove in its under face, a pair of diverging arms arranged below the said drum and having their inner ends joined in the plane of the center of the drum, collar-holding rings slidably mounted on said arms, and means for raising and lowering said arms.

The combination of a standard, a hol low drum supported by the upper end of the standard and having a collarreceiving groove in its under side, a reciprocating rod mounted vertically on the standard in alincment with the center of the drum, a pair of horizontal guides secured to the upper end of the said rod and diverging therefrom, collar-holding rings slidably mounted on the said guides, and. means for reciprocating the said rod.

In testimony that I claim the foregoing as my own, I have hereto a tiixed my signature in the presence of two witnesses.
